Niacin

The primary purpose of niacin (vitamin B3) in your body is to aid in the conversion of food into energy. It also has antioxidant properties. Recent research suggests that niacin may help prevent glaucoma, a disorder in which the optic nerve in your eye becomes injured. Observational research on the nutritional consumption of Korean people and their risk of glaucoma, for example, discovered a link between low dietary intake of niacin and this ailment. Furthermore, an animal study revealed that high dosages of niacin supplementation were useful in the prevention of glaucoma.

More investigation into the potential relationship between niacin and glaucoma is required. Supplements should only be taken with extreme caution. When ingested in high doses of 1.5-5 grams per day, niacin can cause eye problems such as impaired vision, macular degeneration, and corneal inflammation. However, there is no evidence that eating meals rich in niacin has any negative consequences. Beef, chicken, fish, mushrooms, peanuts, and legumes are some food sources.
